Hi,

It seems your DHCP settings are not correct, option 43 using IP addresses for the controllers. AP needs to have Option 43 setup with the HEX values.
To configure the HEX value in DHCP
Under your DHCP pool config
ip dhcp pool Wireless-DHCP-POOL
option 43 [HEX Value]
The HEX Value is 3 values combined
1. f1 (itās always f1)
2. (# of Controllers x 04) So, 3 controllers would be 0C (0C is HEX for 12)
3. The HEX Value of your IP
So here is an example
2 Controllers 1.1.1.1 & 2.2.2.2
1.1.1.1 = 01010101
2.2.2.2 = 02020202
option 43 hex f1080101010102020202
